HOSE-COL!PLBNG.

To all whom it may-concern:

Be it known that I, J OSEPH PE LAR, a citizen of the United States,- residing at Idaho Springs, in the county of Clear Creek and State of Colorado, have invented certain .new and useful Improvements in Hose-Couplings, of which the following is a specification.

My invention relates to hose-couplings especially adapted for use by firemen; and it matically securely ocked in coupled position. "'-'In the accom anying draWinga'fQrminga:

partof this ap ication, and in which siml reference sym cou led. position. Fig. 2 is-a sectional view ont e line 2 f Fig.- 1. vation of the male member shown in the above figures, and Fig. 4 is" an end elevation of the cooperating female member.

Referring to the drawings, 1 indicates the "female memberof a coupling,,having a plurality ofprojectio'nsZ spaced uniformly about its inner periphery and-"provided. with an equal number of similarly-spaced recesses3 A male member in its end surface.

to receive these projections when the parts 4 are brought together. Each groove 5 terminates in an axially inclined or curved groove 6, the grooves 6 tapering gradually in depth from the periphery of the member fl to the bottom of the grooves 5, as shown especially in Fig. 2. This tapering of the grooves 6 provides them Withbottoms eccentric to the axis of the male member 4, whereby the pro-' Specification of Letters Patent.

to provide a ols indicate correspondin parts in the several vie-ws,x Figure 1 is an a'Xi section taken on the line 11 of'Fig. 2, showing one embodiment of my inventiondn its Fig. 3 is a side ele- 4- is shown provided with -.a pluralityof axially extending recesses 5, [which are equal in number to the projections Qofthe female member and properly spaced Patented Nev. 20, 1906.

jeotions 2 Will be forced into tight engagement with the bottoms of said grooves for augmenting the rigidity and strength of the coupling.

Aflan e 7 onthe member 4 carries a springpressed ocking-pin 8., which is so positioned relative to the grooves 6 that it .will engage one of the recesses 3 when the parts of the coupling are connected together With=the projections 2 in said grooves. The lockingpin 8 is shown provided with a head-comprisin "a conical guiding portion 9' and a cylindrical locking ortion 10. B this construc, tion the conica portion 9 readlly enters either of .the recesses 3 brought adjacent thereto, and the cylindrical portion 10 is thereby guided into such recess for securely locking the two members against relative rotation.

The members 1 and 4 are rovided respectively, with a nipple l1 and 12, to which are clamped, or'otherwise suitably secured,-

the ends of the hose lengths. A washer 13 is;-

positioned'ag-ainst the nipple 11 of the mend-j bef'l'for engaging the end of the member saidmember being forced tightly against the washer by' the engagement of theprojeotions '2 withthe axially-inclined grooves 6.

, Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is a 1. Ina hose coupling,'th e combination of two telescoping members, ,the first of said members provided with a series of projections and asimilar series of recesses, the second of, said members provided with a series of grooves for IQCGlVlIlg sald several pro ections, said grooves terminatingin axiallyinclined grooves provided with eccentricallyarranged bottoms for firmly engaging said projections, -and a locking means carried by said second member-for, engaging one of the recesses in said first member, substantially as described.

2. In 'a'hose-coupling, the combination of two telescoping members, the first of said members provided with a series of projections-and a similar series of recesses, the second. ofsaid members provided with a series of grooves'for receiving said several projections, said grooves terminating 1n axially- IOO i into such recess and Witlra cylindrical orinclinedgrooves z mviided Witheccentricallythe two members against relativerota'tion,
